Adaptation a structure or behavior that helps a living thing live in its surroundings.

Adapted made fit to live under certain conditions.

3What is an adaptation?

An adaptation is a change in an animals physical structure or behavior that helps an animal to survive in their habitat.

Examples The shape of a birds beak, number of fingers and toes, or the color of an animals fur.

Physical adaptations do not develop during one lifetime, but over many generations.

4Example of Adaptation

The shape of an animals teeth is related to its diet.

Herbivores, such as deer, have many molars for chewing tough grass and plants.

Carnivores, such as lions, have sharp canines to kill and tear meat.

5Who experiences adaptations?

All species have experienced adaptation and will continue to slowly adapt as the next generations are born.

We will identify certain species from each of these groups and the reasons for their success

Mammals

Birds

Reptiles

Amphibians

6Mammals

Endothermic or

warm-blooded

All have some type of hair

Some are very specialized, such as white polar bear fur

Method of locomotion

Care for young

7Birds

Leg Length

Roseate Spoonbill (top right)

Foot Webbing

Laughing Gull (top left)

Beak Shape

Long Billed Curlew (bottom)

8Reptiles

Ectothermic or cold- blooded

Scales

Some undergo hibernation and estivation

Lay eggs on land

Leg structure and position

9Amphibians

Ectothermic

Lay eggs in water

Partially of fully webbed feet

Have lungs or can absorb oxygen through their skin

10Animal Defense

Some animals use these methods of defense to protect themselves

Camouflage

Snake

Mimicry

Mexican Milk Snake

Bright colors

Skunk and Poison Arrow Frog

Hair projections

Hedgehog quills

Deer Antlers

11Adaptation Applications Lions

Why are the eyes of a lion set in front of the head rather than on the sides?

Answer Eyes in front of the head allow for depth perception and ability to judge distances when hunting.

12Adaptation Applications Lions

What is the purpose of the mane on a male lion? What is the reason for the lions color?

A thick mane helps the male to appear larger and serves as protection for the throat. The tawny brown coat color camouflages the animal and young among vegetation.

13Adaptation Applications Giraffe

Why are giraffes able to go for long periods of time without water?

Answer Giraffes drink water when available, but can go weeks without it. They rely on morning dew and the water content of their food.

14Adaptation Applications Giraffe

How are their long necks adapted to their lifestyle?

Answer This extra length is thought to have evolved to help the giraffe spot predators and other giraffes in the distance. Interestingly, giraffes and humans have the same number of vertebrate in their necks.

15Adaptation Applications Zebras

How do zebras defend themselves?

Capable of running up to 40 mph. Zebras defend themselves by kicking and biting. Coloration also plays a role in evading predators, although theories have not reached an agreement.

17What is hibernation?Why do animals hibernate?

This is a very special kind of deep sleep

It is brought on by short day lengths, cold temperatures and food shortages

It is a survival strategy

Dropping into a deep hibernation means animals are using less energy

Food is scarce

Animals miss the cold seasons

18How do animals prepare for hibernation?

They try to put on as much fat as possible because they wont be eating much during the winter

This is called brown fat, which is found across the back and shoulders, close to an animals organs

Brown fat works hard to deliver quick energy to an animal coming out of hibernation

19Can you think of any animals that hibernate?

Bear

hedgehog

Ladybird

Snake

Squirrels

Bats
